RollBotz RoboKone Filler Bead Grinding Mill with Funnel USB Chargeable Supreme Red

When I first saw a photo of this thing I thought it looked like a tattoo gun. I couldn’t imagine how it could work for filling cones. It’s actually very well thought out technology and it works perfectly as advertised. First question I asked myself how did I live this long without this item? 😎

I don’t understand the negative reviews this thing is magic!!! Best invention ever! Everyone should buy one! Works perfectly and the pre roll cones come out perfect in seconds. I’m buying more to gift them to friends. Saves so much time and energy having to hand grind and fill it.

The Rollbotz grinder and filler is great. It’s pretty quiet and easy to clean. I recommend to all who would find it a great value for a great product for grinding flower and immediately packing a cone.

UPDATE: I was able to charge this item once. 2nd charge, the light doesn’t come on when i plug it in. i let it charge overnight (at least 10 hours) and the battery wouldn’t last long enough for one cone. I am sorely disappointed because i was really getting the hang of using this thing. One star, the product went bad one day after the return window. I plan on reaching out to the company to see what they can do for me. If they appropriately rectify this situation i will update my review.i absolutely love this product. it just arrived today, so i cannot attest to the longevity of it (at this price, im not too concerned). however, i can say without a doubt this is the best gadget for cones hands down. the grinding mechanism works fantastic, the versatility to use shorties and king cones is great, and the overall function of this gadget is going to save me so much time and herb. i tend to be heavy handed when packing cones and this is going to provide me with an even and (relatively) consistent pack every time. the sequence of events and handling take some getting used to but i was able to fill 10 cones in no time at all once i got the hang of it. i will probably order some of those specialty pipe cleaners to reach the narrowest part of the tube where the included brush can’t reach. if i could knock off half a star for this i would, but this product is beneficial in so many other ways and this is a simple fix, so five stars from me.

Takes the work outta grinding,quick and easy ..it's not a perfect cone set up every time but it'll have to do...

The media could not be loaded. Works great! I let it charge some first and boom! It did what it needed to do! Very easy to use. A little larger than expected but it is durable so far. I’ve accidentally dropped it twice and it just bounced and rolled. Great grind quality and a little goes a long way!

Was super excited about this grinder. We have used similar (ball and chain style) grinders in the past and loved them so when I saw this with the cone filling funnel for the price point I was excited to give it a try. The grinder works great. Good quality, durable/thick plastic. Easy to charge and use, But sadly the tip is just slightly too big to fill my 110mm king size cones as the product claims. I expected it to be a tight fit but I’ve tried to different brands of cones with it and the tip is just too big. I grinding onto a try and filling it with a funnel like I was doing before :(.

This has to be the best invention made for quick cone filling. This machine is powerful when fully charged and the charge can last a very long time. I would say I used it daily for about 5 days, and I recharged it without it ever needed it yet. You do have to clean it often since it does grind pretty finely, it does accumulate a tone of dust on the inside that will make it sticky. Just clean it every 1/2 oz or so after grinding with some alcohol wipes or just alcohol and paper towels to keep it clean and running like new. Make sure to place something under the funnel while it's grinding for any fallout. Enjoy! I recommend!
